Abiomed has issued a warning about an issue with its Automated Impella Controller devices following a reported patient death. The issue stems from a manufacturing defect in certain units’ pump driver circuit assemblies, which contain capacitors rated below required specifications, according to an Aug. 27 news release from the FDA.
